🇨🇴 MapBiomas Colombia – Mining

Developed by MapBiomas Colombia.

📖 About

This repository contains the scripts to classify and filter mining areas (Class 30) across the Colombian territory as part of the MapBiomas Colombia Collection 3 cross-cutting themes.

We highly recommend reading the Colombia Collection 3 Appendix of the Algorithm Theoretical Basis Document (ATBD). The fundamental information about the classification methodology is there.
